C5a,Complement Component 5a
Mouse C5a, His Tag (C5A-M51H4) is expressed from E.coli cells. It contains AA Asn 679 - Arg 755 (Accession # P06684).
Predicted N-terminus: Met
This protein carries a polyhistidine tag at the N-terminus.
The protein has a calculated MW of 10.9 kDa. The protein migrates as 14 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
Less than 1.0 EU per μg by the LAL method.
>95% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

Mouse C5a, His Tag on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 95%.
Immobilized Mouse C5a, His Tag (Cat. No. C5A-M51H4) at 2 μg/mL (100 μL/well) can bind Anti-C5a (Human IgG1) with a linear range of 0.4-6 ng/mL (QC tested).
Complement Component C5a (C5a) is also known as C5,and is a protein fragment released from complement component C5.,is a potent chemotactic factor for human peripheral blood neutrophils and monocytes, and is believed to play an important role in a number of inflammatory conditions. There are several functions in the below: C5a is an anaphylatoxin, causing the release of histamine from mast cells; C5a is effective leukocyte chemoattractants, causing the accumulation of white blood cells, especially neutrophil granulocytes, at sites of complement activation; C5a activates white blood cells by increasing avidity for white blood cell integrins and upregulating the Lipoxygenase pathway for arachidonic acid metabolism; C5a is a powerful inflammatory mediator, and seems to be a key factor in the development of pathology of many inflammatory diseases involving the complement system; C5a modulates balance between activating versus inhibitory IgG Fc receptors on leukocytes, thereby enhancing autoimmune response.
